Element: setAttributeNS() method
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
setAttributeNS
adds a new attribute or changes the value of an attribute
with the given namespace and name.
If you are working with HTML documents and you don't need to specify the requested attribute as being part of a specific namespace, use the setAttribute()
method instead.
Syntax
js
setAttributeNS(namespace, name, value)
Parameters
Return value
None (undefined
).
Examples
js
let d = document.getElementById("d1");
d.setAttributeNS(
"http://www.mozilla.org/ns/specialspace",
"spec:align",
"center",
);
Notes
setAttributeNS
is the only method for namespaced attributes which expects
the fully qualified name, i.e. "namespace:localname"
.
